NAME
SNMP::Info::MAU - SNMP Interface to Medium Attachment Unit (MAU) MIB (RFC 2668) via SNMP
AUTHOR

SYNOPSIS
my $mau = new SNMP::Info (
AutoSpecify => 1,
Debug => 1,
DestHost => 'hpswitch',
Community => 'public',
Version => 2
);
my $class = $mau->class();
print " Using device sub class : $class\n";
DESCRIPTION
SNMP::Info::MAU is a subclass of SNMP::Info that supplies access to the MAU-MIB (RFC 2668). This MIB is
sometimes implemented on Layer 2 network devices. MAU = Medium Attachment Unit.
The MAU table contains link and duplex info for the port itself and the device connected to that port.
Normally you use or create a subclass of SNMP::Info that inherits this one. Do not use directly.
For debugging purposes call the class directly as you would SNMP::Info
my $mau = new SNMP::Info::MAU(...);
Inherited Classes
None.
Required MIBs
MAU-MIB
IANA-MAU-MIB
GLOBALS
These are methods that return scalar value from SNMP
None
TABLE METHODS
These are methods that return tables of information in the form of a reference to a hash.
$mau->mau_i_duplex()
Parses mau_index and mau_link to return the duplex information for interfaces.
$mau->mau_i_duplex_admin()
Parses "mac_index","mau_autostat","mau_type_admin" in order to find the admin duplex setting for all
the interfaces.
Returns either (auto,full,half).
$mau->mau_i_duplex_admin_old()
Called by mau_i_duplex_admin() if "mau_type_admin" is empty. Parses
"mau_index","mau_autostat","mau_autosent" in order to find the admin duplex setting for all the
interfaces.
Returns either (auto,none,full,half).
$mau->mau_i_speed_admin()
Returns admin speed setting for all the interfaces.
MAU Interface Table Methods
$mau->mau_index() - Returns a list of interfaces and their index in the MAU IF Table.
("ifMauIfIndex")
$mau->mau_link() - Returns the type of Media Access used.
This is essentially the type of link in use.
eg. dot3MauType100BaseTXFD - 100BaseT at Full Duplex
("ifMauType")
$mau->mau_status() - Returns the admin link condition as
1 - other
2 - unknown
3 - operational
4 - standby
5 - shutdown
6 - reset
Use 5 and !5 to see if the link is up or down on the admin side.
("ifMauStatus")
$mau->mau_up() - Returns the current link condition
(C<ifMauMediaAvailable>)
$mau->mau_type() - Returns a 32bit string reporting the capabilities of the port from a MAU POV.
Directly from F<MAU-MIB> :
Bit Capability
0 other or unknown
1 AUI
2 10BASE-5
3 FOIRL
4 10BASE-2
5 10BASE-T duplex mode unknown
6 10BASE-FP
7 10BASE-FB
8 10BASE-FL duplex mode unknown
9 10BROAD36
10 10BASE-T half duplex mode
11 10BASE-T full duplex mode
12 10BASE-FL half duplex mode
13 10BASE-FL full duplex mode
14 100BASE-T4
15 100BASE-TX half duplex mode
16 100BASE-TX full duplex mode
17 100BASE-FX half duplex mode
18 100BASE-FX full duplex mode
19 100BASE-T2 half duplex mode
20 100BASE-T2 full duplex mode
("ifMauTypeList")
$mau->mau_type_admin()
("ifMauDefaultType")
$mau->mau_auto() - Indicates whether or not auto-negotiation is supported.
("ifMauAutoNegSupported")
$mau->mau_autostat() - Returns status of auto-negotiation mode for ports.
("ifMauAutoNegAdminStatus")
$mau->mau_autosent() - Returns a 32 bit bit-string representing the capabilities we are broadcasting on
that port
Uses the same decoder as $mau->mau_type().
("ifMauAutoNegCapAdvertised")
$mau->mau_autorec() - Returns a 32 bit bit-string representing the capabilities of the device on the
other end.
Uses the same decoder as $mau->mau_type().
("ifMauAutoNegCapReceived")
SET METHODS
These are methods that provide SNMP set functionality for overridden methods or provide a simpler
interface to complex set operations. See "SETTING DATA VIA SNMP" in SNMP::Info for general information
on set operations.
$mau->mau_set_i_speed_admin(speed, ifIndex)
Sets port speed, must be supplied with speed and port "ifIndex".
Note that this method has some limitations since there is no way to reliably set the port speed
independently of the port duplex setting on certain devices, notably the Cisco Cat4k series.
Speed choices are '10', '100', '1000', 'auto'.
$mau->mau_set_i_duplex_admin(duplex, ifIndex)
Sets port duplex, must be supplied with duplex and port "ifIndex".
Note that this method has some limitations since there is no way to reliably set the port duplex
independently of the port speed setting on certain devices, notably the Cisco Cat4k series.
Duplex choices are 'auto', 'half', 'full'.
$mau->mau_set_i_speed_duplex_admin(speed, duplex, ifIndex)
Sets port speed and duplex settings, must be supplied with speed, duplex and port "ifIndex".
Accepts the following values for speed and duplex:
Speed/Duplex
------------
auto/auto (this is a special case)
10/half
10/full
100/half
100/full
1000/half
1000/full
Utility Functions
munge_int2bin() - Unpacks an integer into a 32bit bit string.
$mau->_isfullduplex(bitstring)
Boolean. Checks to see if any of the full_duplex types from mau_type()
are high. Currently bits 11,13,16,18,20.
$mau->_ishalfduplex(bitstring)
Boolean. Checks to see if any of the half_duplex types from mau_type()
are high. Currently bits 10,12,15,17,19.
